Patent NO-151979-B (NO)
Inventor: MILZ ARTHUR
IPC: F04D29/44
Filed: 1980-04-08
Abstract: The disclosure relates to a rotary pump especially for corrosive liquids including an impeller rotating in a working chamber. A spirally wound duct leads from one surface of the working chamber to the outlet pipe of the pump. The upstream end of the duct obliquely enters the working chamber, whereby the end portion of the duct is laterally open towards the chamber and forms a channel in the wall of the chamber. The duct winds helically around the rotation axis of the impeller, having an inside wall at a progressively decreasing radial distance from said rotation axis and a progressively increasing pitch when viewed in the direction of the flow. A feature is the provision of the wound duct in the form of a helix as an open groove formed on the outer surface of a solid stator body and closed by an encompassing casing. A further feature is the provision of a relatively loose, elongated drive shaft from a motor to the pump impeller disposed within a guide tube and a circumferential clearance between the shaft and the tube for leakage flow of liquid being pumped to lubricate the shaft wherein a bypass port is provided in the guide tube for return of the leakage flow upstream of a restriction in the clearance. The restriction increases pressure in the clearance to dampen lateral oscillation of the shaft in the tube. No seals are used for the shaft thereby precluding the tendency of seals to stick during prolonged rest periods.

IPC: B29L22/00
Filed: 1986-01-24
Abstract: The apparatus of the invention, which is particularly adapted for being applied to a continuous rotary hot-molding machine for forming trays (V) or any other containers of a relatively limited depth from a foil (9) of foamed plastics, is provided for internally embossing the bottom walls of said trays. The apparatus comprises elements constructed in form of wheels, which are one for each single longitudinal row of cavities (104) of the multiple molds (4), and which are keyed to a rotary shaft (11) arranged parallel to the shaft (2) of the mold-carrying drum (1) in the hot-molding machine, and perpendicularly to the forward direction of the foil. Each one of these wheel elements carries in its periphery any desired number of dies (4) (or plug) having a lateral profile that is curvilinear (or is like a circle arc, or is differently shaped), and spaced apart according to the distance between the single multiple mold cavities upon which they act, and having their outer surface provided with special embossing projections (15) or recesses. Of course, the size of each die (14) is not greater than the size of the bottom wall of a tray V to be embossed. The thus formed embossing devices are urged with a suitable pressure against the molds, and are rotated in the direction opposite to the mold-carrying drum in the rotary hot-molding machine, at such a speed that each die will act upon the bottom of one cavity of the multiple mold, (4), and that the peripheral speed of the embossing die and the speed of the bottom wall of a tray to be embossed, contained in the mold cavity, be the same or sensibly the same at the contact area, the whole in such a manner that the dies will rotate with no slippage in the mold cavities, to pressure-emboss the bottom walls of the trays during the hot-molding step.
